提出了一种用于可穿戴无线传感器和个人设备的动能采集器。该采集器基于人体运动的电磁传导和具有智能开关的电荷泵，以最大限度地缩短从完全耗尽状态的启动时间。还介绍了人体运动典型频率范围内的详细分析和设计优化。实验结果证实，所提出的方法大大减少了启动时间，并且可以有效地利用甚至很小的运动。
A kinetic energy harvester for wearable wireless sensors and personal devices is proposed. The harvester is based on electromagnetic transduction of human movements and on a charge pump with smart switching to minimize the start-up time from the fully depleted state. A detailed analysis and design optimization in the frequency range typical of human motion is also presented. Experimental results confirm that the proposed approach sharply reduces the start-up time and can exploit efficiently even small movements.
